First of all thanks for this wonderful grid.

Following the examples I've been able to display data and a few tools like search, edit, etc.

Now I'm trying to make searching work using the example (search_adv.php) found in the jqgrid_demo36.zip file, but I have a doubt:

I found this line in the code:

$examp = $_REQUEST[“q”]; //query number

What is this for? I'm getting an error because $_REQUEST['q'] isn't defined, which is logical because the grid never sends a parameter 'q'. What am I doing wrong?? Thanks in advance for any help.
